package another installer with vb.net msi deployment package

[lminmei]

first i need to check the system for an existing .dll or .ocx file... and if its not present on the system... the msi installer needs to open or call another ex: "setup_controls.exe" to install the necessary dlls first before installing the main application.

has anyone ever done this before?
please help...
thanks derek

And why not just install the dll and ocx every time that way you are sure it is installed.

because i'm working with ESRI GIS products and it requires a runtime installer...
the individual ocx and dll will not register for some reason...
plus the full runtime installer will install other dlls which i'm not sure of
come on, there's gotta be a way to do this in the VS.NET deployment packager...
